Maintenance

Cleaning the inside

During the printing process, paper, toner, and dust particles can accumulate inside the machine.
This buildup can cause print quality problems, such as toner specks or smearing. Cleaning the inside
of the machine clears and reduces these problems.
1. Turn the machine off and unplug the power cord. Wait for the machine to cool down.
2. Open the front door and pull the toner cartridge out. Set it on a clean flat surface
3. With a dry, lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area.
4. Locate the long strip of glass (LSU) inside the top of the cartridge compartment and gently clean
the glass with a swab.

To prevent damage to the toner cartridge, do not expose it to light for more than a few
minutes. Cover it with a piece of paper, if necessary.
Do not touch the green surface underside of the toner cartridge. Use the handle on the
cartridge to avoid touching this area.
While cleaning the inside of the machine, be careful not to damage the transfer roller or any
other inside parts. Do not use solvents such as benzene or thinner to clean. Printing quality
problems can occur and cause damage to the machine.
